MAXIMUM VANADIUM CONTENT IN ASTM A333 Gr.6
MAXIMUM VANADIUM CONTENT IN ASTM A333 Gr.6
(OP)
Vanadium(V) with Niobium(Nb) is usually used to have fine grane and solubilization properties on carbon steel. The common limit used for both is 0,15%. I need to be compliant with a specification that limits the Vanadium content belove 0,05% while a Vendor offer me a Carbon steel ASTM A 333 Gr.6 with Vanadium at 0.07%. Is that acceptable for a low temperature carbon steel. Why the specification asking for such low limit?

Since vanadium is a potent strengthener and will affect low temperature notch toughness behavior, the Purchaser is purposely limiting this content and other microalloy additions. Grain refinement is provided by aluminum, per specification.

This could be a case of the specification writer trying to anticipate every potential metallurgical issue by writing such a tight specification that he shrinks the cost/availability window.
